We characterised five transiting planetary systems (HAT-P-3, HAT-P-12,HAT-P-22, WASP-39 and WASP-60) and determined their sky-projected planetorbital obliquity through the measurement of the RM effect. We used HARPS-Nhigh-precision radial velocity measurements, gathered during transit events, tomeasure the RM effect in the target systems and determine the sky-projectedangle between the planetary orbital plane and the stellar equator. Thecharacterisation of stellar atmospheric parameters was performed exploiting theHARPS-N spectra, using line equivalent width ratios, and spectral synthesismethods. Photometric parameters of the five transiting exoplanets werere-analysed through 17 new light curves, obtained with an array of medium-classtelescopes, and other light curves from the literature. Survey-time-seriesphotometric data were analysed for determining the rotation periods of the fivestars and their spin inclination. From the analysis of the RM effect we deriveda sky-projected obliquity of 21.2 degree, -54 degree, -2.1 degree, 0 degree and-129 degree for HAT-P-3b, HAT-P-12b, HAT-P-22b, WASP-39b and WASP-60b,respectively. The latter value indicates that WASP-60b is moving on aretrograde orbit. These values represent the first measurements of \lambda forthe five exoplanetary systems under study. The stellar activity of HAT-P-22indicates a rotation period of 28.7 days, which allowed us to estimate the truemisalignment angle of HAT-P-22b, \psi=24 degree. The revision of the physicalparameters of the five exoplanetary systems returned values that are fullycompatible with those existing in the literature. The exception to this is theWASP-60 system, for which, based on higher quality spectroscopic andphotometric data, we found a more massive and younger star and a larger andhotter planet.
